I think both doctors and patients would want a different system for both doctors and patients. Having seen a poor performing medical system, and comparing it with the US medical system, all I can say it's that the US one doesn't seem designed to optimize health and well being of patients and, based on reading several articles representing doctors opinions, neither doctors'.
I do think it's maximially optimized to extract revenue. That can sometimes be good (e.g. good access to healthcare) but often times it's not great.
Given healthcare, along with education should be a national priority, both should be heavily "configured" to serve peoples' goals first and any financial goal should be secondary (although arguably useful).
I suspect the current shareholder structures from hedge funds are (intentionally or not) driving things in the wrong direction wrt to public health goals. This is article from a few days ago is also interesting https://news.ycombinator.com/item?id=45680695
